Though truly profitable, ICOs are considered scams by many but there are few that are truly legitimate. Just the right choice for China because these ICOs are targeting the people of their country because there are many crypto currency investors in China.
Unless it has long term success, ICOs are only profitable to early adopters (if the token is not launched below the ICO price, of course...) and a few other investors who buy before the pump.
The point is, it's not hard to understand that most ICOs will not have long term success, and many people will have to learn the hard way.
No ICO's that specifically targeting China, it targets the whole world especially those who really in the cryptocurrency scene now, I really don't know why Chinese government made a move like this to their citizens, it seems that their cyber authorities is so great that they can monitor every financial flow in their economic growth and see that most of the money of their people is moving inside the crypto world.
For me ICO's are simply risking your money because you trusted that company who made that platform to be successful in the future, unless you are just investing blindly that you will not take time to study what is the background of the ICO itself.
